Still no luck, even on a box with a igb-driven NIC (I350): [ 667.928036] rt_igb 0000:06:00.1: Intel(R) Gigabit Ethernet Network Connection [ 667.928064] rt_igb 0000:06:00.1: rteth0: (PCIe:5.0Gb/s:Width x4) 00:25:90:5d:10:19 [ 667.928149] rt_igb 0000:06:00.1: rteth0: PBA No: 010A00-000 [ 667.928153] rt_igb 0000:06:00.1: Using MSI-X interrupts. 1 rx queue(s), 1 tx queue(s) xeon-d:~ # cat /proc/xenomai/irq IRQ CPU0 ... CPU15 47: 0 ... 79 rteth0-TxRx-0 I'm currently using the two attached patches on top of ipipe-core-4.19.57-x86-3. Did you cross-check if the running kernel contains the fix(es)?
